A Light In The Field

In his evocative debut novel, Light on a Part of the Field, Kevin Holowack introduces us to a family grappling with artistic ambition, mental illness, and rifts that may not be possible to mend. Set in B.C. and Alberta in the 1960s and 1970s, this is a novel of finely observed vignettes offering a refracted look at art and family in the Canadian West. A young artist, Ruth, and her obsessive husband are struck by lightning, an experience that throws their lives into a universe of intense beauty and angst. Years later, Ruth lives on a farm her husband bought before his mysterious disappearance, and she creates idyllic but unremarkable paintings to cope with her confusion and loss. Then, without warning, her eldest daughter Gayle is love-struck by a travelling stranger and runs off to Edmonton where she too must contend with poverty, sickness, and her father's upsetting legacy. Meanwhile, farm-bound Ruth becomes more frantic in her work and begins longing for human contact as her house and animals disintegrate around her. As Gayle and Ruth seek new ways of connecting in order to remedy their unsettling family legacy, they begin a complicated process of renewal and must decide whether they can reconcile despite all the pain they have caused one another.

At one point in her life, author Ana Lior was in an induced coma. When she woke, she was filled with the idea of the love and light energy field and the happiness experiment. Lior had gained an entirely new understanding of who God is and how much a life of contribution meant to her. In The Love and Light Field, she shares one of the most powerful energy fields she has discovered as well as the powerful tool of transmutation with which to access the field. Lior provides instructional material on how to raise your frequency as well as instant downloads that enter your energy field directly as you read them. These downloads have been channeled through Lior from God, nature, and source. Comprehensive and easy to read, The Love and Light Field offers a download of good vibes. It seeks to create miracles in your life and others’ lives and change your attitude toward your life, making your whole existence a pleasurable experience.

Light field is one of the most representative image-based rendering techniques that generate novel virtual views from images instead of 3D models. The light field capture and rendering process can be considered as a procedure of sampling the light rays in the space and interpolating those in novel views. As a result, light field can be studied as a high-dimensional signal sampling problem, which has attracted a lot of research interest and become a convergence point between computer graphics and signal processing, and even computer vision. This lecture focuses on answering two questions regarding light field sampling, namely how many images are needed for a light field, and if such number is limited, where we should capture them. The book can be divided into three parts. First, we give a complete analysis on uniform sampling of IBR data. By introducing the surface plenoptic function, we are able to analyze the Fourier spectrum of non-Lambertian and occluded scenes. Given the spectrum, we also apply the generalized sampling theorem on the IBR data, which results in better rendering quality than rectangular sampling for complex scenes. Such uniform sampling analysis provides general guidelines on how the images in IBR should be taken. For instance, it shows that non-Lambertian and occluded scenes often require a higher sampling rate. Next, we describe a very general sampling framework named freeform sampling. Freeform sampling handles three kinds of problems: sample reduction, minimum sampling rate to meet an error requirement, and minimization of reconstruction error given a fixed number of samples. When the to-be-reconstructed function values are unknown, freeform sampling becomes active sampling. Algorithms of active sampling are developed for light field and show better results than the traditional uniform sampling approach. Third, we present a self-reconfigurable camera array that we developed, which features a very efficient algorithm for real-time rendering and the ability of automatically reconfiguring the cameras to improve the rendering quality. Both are based on active sampling. Our camera array is able to render dynamic scenes interactively at high quality. To the best of our knowledge, it is the first camera array that can reconfigure the camera positions automatically.

In bright light, it is easier to take a beautiful photograph with your DSLR. When the sun starts to go down or you are shooting indoors, a whole new skill set is needed. This new addition to the successful Field Guide Series will help you shoot what potentially could be the most lovely image without the help of natural light. No more harsh flash photographs with dreary backgrounds and no more blurry night shots that were exposed too long. Opening with a section on the qualities of different kinds of low light, the book then deals with ways of overcoming gloomy situations, whether you are shooting hand-held or on a tripod. Post-production fixes are also covered, allowing you to turn difficult shots into real works of art.

Light at the Edge of the Field keeps readers wanting more as a pitcher's girlfriend confronts her lover, not about his obsession with baseball but about their relationship and future together. After watching a traveling African American baseball team, a father is forced to inform his innocent young son about small-town racism. An insightful, empathetic wife guides her husband through the most difficult challenge he will ever face in baseball: his own retirement from it. A disadvantaged, fleet-footed player in Mexico dreams of making it to the Major Leagues. Though he can catch pitches consistently for hours, a diligent catcher drops the ball in his relationship with his girlfriend. These are just a few of the compelling characters readers will discover as they step into the batter's box. This tour de force of baseball short stories reveals insights not only about the game of baseball, but the game of life. Meissner's previous baseball collection, Hitting into the Wind, was hailed as "A quiet masterpiece of baseball writing." As they round the bases, these new stories will follow in those footsteps. Like a baseball's cushioned cork core, the stories illuminate what's central to our lives--our dreams, both those that can be reached, and those which remain unreachable.

This book presents and describes a series of unusual and striking strong-field phenomena concerning atoms and free electrons. Some of these phenomena are: multiphoton stimulated bremsstrahlung, free-electron lasers, wave-packet physics, above-threshold ionization, and strong-field stabilization in Rydberg atoms. The theoretical foundations and causes of the phenomena are described in detail, with all the approximations and derivations discussed. All the known and relevant experiments are described too, and their results are compared with those of the existing theoretical models.An extensive general theoretical introduction gives a good basis for subsequent parts of the book and is an independent and self-sufficient description of the most efficient theoretical methods of the strong-field and multiphoton physics. This book can serve as a textbook for graduate students.

This book provides a comprehensive guide to 3D Light-Field camera based imaging, exploring the working principles, developments and its applications in fluid mechanics and aerodynamics measurements. It begins by discussing the fundamentals of Light-Field imaging and theoretical resolution analysis, before touching upon the detailed optics design and micro-lens array assembly. Subsequently, Light-Field calibration methods that compensate for optical distortions and establish the relations between the image and real-word 3D coordinates are covered. This is followed by Light-Field 3D reconstruction algorithms which are elaborated for micrometer-scale particles and centimeter-scale physical models. Last but not least, implementations of the preceding procedures to selected fundamental and applied flow measurement scenarios are provided at the end of the book. Development and Application of Light-Field Cameras in Fluid Measurements gives an in-depth analysis of each topic discussed, making it ideal as both an introductory and reference guide for researchers and postgraduates interested in 3D flow measurements.
